Subject[PATCH v2 2/3] iio: cros_ec: Allow enabling/disabling calibration mode
Date
calibration was a one-shot event sent to the sensor to calibrate itself.
It is used on Bosch sensors (BMI160, BMA254).
For TCS3400 light sensor, we need to stay in calibration mode to run
tests.
Accept boolean true and false (not just true) to enter/exit calibration.
